Abstract
A continuous process for producing ethanol by fermenting carbohydrate containing feed stocks at atmospheric pressure in a fermentor, in which a fermentation liquor stream is withdrawn from the fermentor, a yeast concentrate is recovered from said stream both recycled to the fermentor and the yeast-free remainder treated to remove ethanol and leave a stillage stream, a large portion of which is recycled to the fermentor, enabling high concentration of fermentable material to be supplied to the fermentor and reducing the amount of water required for the process.
